WEB-ASSOCIATING MECHANISM.

Specification of Letters I atent. t t June 10, 1919,

Application filed July 18, 1916. Serial No. 109,951.

To all whom it may concern:

Be it known that I, HOWARD M. BARBER, a citizen of the United States, and resident of Stonington, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Web-Associating Mechanisms, of which the following is a specification.

The object of this invention is to provide a web associating mechanism which may cut a wide web into a plurality of narrow webs of different widths to suit products having pages of difi'erent widths, and to assoclate said narrow webs.

In carrying out the above object, means are provided for adjusting, laterally of the machine, the positions of the web slitters, the turners and the web feeding rolls.

A practical embodiment of my lnvention is represented inthe accompanying drawings, in which:

Figure 1 is a detail view in side elevation of so much of a web folding machine as will illustrate my improved associating mechanism.

Fig.

Figs.

2 is a front view of the same,

3 and 4 are respectively enlarged detail side and back views of the means for adjusting the turners laterally of the machine,

Fig. 5 is a detail sectional view on a similar scale, showing the laterally adjustable feed rolls adjacent to the points of the turners and the feed rolls immediately below the first named feed rolls, and

Fig. 6 is a detail sectional View on a similar scale, the said feed rolls and turners being shown in full lines at the limits of their adjustment laterally of the machine in one direction and in dotted lines at the limits of their adjustment in the other direction, the positions in full lines being the adjustments for the widest na'rrow webs and in dotted lines for the narrowest narrow webs within the limits of the machine as illustrated.

The mechanism is adapted for use in connection with a single wide web or a plurality of superimposed wide webs, as desired. In the present instance a single wide web is shown for purposes of illustrating the invention.

This wide web 1, passes around a web tightening roll 2, mounted between suitable arms 3 of a rock lever, the shaft 4 of which is pivoted to the machine frame. A manroll 10, by means of a plurality of slitters 11 having their shaft suitably mounted in arms 12 carried by a cross-bar 13 of the machine frame. In the present instance I have shown the wide web as being divided into seven narrow webs by six of these slitters 11.

The slitters 11 are individually adjustable along their shaft laterally of the machine, to slit narrow webs of different widths from the wide web.

- The narrow webs pass from the slitting roll 10, over the roll 14, and from thence downwardly over the single turners 15, which single turners are individually adj ustable laterally of the machine to correspond to the widths of the narrow webs, as, for instance, by the following means.

The cross bar 16 of the machine frame is provided with two horizontal elongated slots 17 therethrough, through which slots bolts 18 pass, which serve to bolt the turner bracket 19 to the cross-bar 16. To provide .a micrometer adjustment for swinging the top of the turner 15 to slightly change its angle, the following arrangement is provided: The screw 20 is journaled in the bracket 19 and is held against longitudinal movement by the collars 20*. The screw 20 has a threaded engagement with the turner bracket 21, which bracket has elongated slots through which the tightening bolts 22 pass. These bolts are loosened to permit the swinging of the turner by the turning of the screw 20.

The point of the turner is supported in the usual manner, by the bar 23 which connects it with the depending arm 24 of the bracket 19. This bar 23 is also adjustable by the manipulation of the nuts 25, to accurately adjust the point of the turner outwardly and inwardly.

The feed rolls adjacent to the points of the turners are denoted by 26, and are individually adjustable to narrow webs of different widths, as follows:

The front and rear cross frames 27, 28,

of the machine frame are provided with tracks 29, 30, having undercut grooves 31, 32, running the lengiths of the tracks, in which grooves are located the heads of pairs of bolts 33, 34, of the front and rear bearings 35, 36, respectively, for the shafts of the rolls 26. These bolts 33 and 34 are provided with suitable nuts 37, 38, for clamping the bearings 35, 36, in the desired adjustment laterally of the machine. The tracks 29, 30, may be provided with a suitable scale and the bearings with a suitable mark for bringing the different feed rolls 26 rapidly into theirrespective adjustments.

Similarly, a plurality of feed ,rolls 39 are located immediately below the feed rolls 216, which feed rolls 39 are individually adjustable laterally of the machine by providing the front and rear cross frames 27 and 28 with tracks 40, 41, having undercut grooves 42, 43, for receiving the heads of the bolts 44, 45, of the bearings 46, 47, for the shafts of said rolls 39. These bolts 44, 45, are also provided with the fastening nuts 48, 49, for securing these bearings in their proper positions Also the tracks 40, 41, may be provided with a suitable scale and the bearings with suitable marks for insuring the accuracy of the adjustment.

These narrow webs as they leave the feed rolls 39, pass around fixed and bodily movable intermediate feed rolls onthoir way to the pairs of associating rolls 50, 51; 54, 55, where the associated webs may be led to a suitable cutting and folding mechanism, not shown herein. V The fixed intermediate feed rolls are denoted by 56, and the bodily movable intermediate feedrolls are denotedby 57. Each of these bodily movable intermediate feed rolls 57 is mounted between suit-able arms 58 carried by a rock shaft 59, mounted in the cross frames'27, 28, which rock shaft 59 is provided at the front of the machine, with a worm wheel 60 which meshes with a worm 61, the shaft of which'worm is provided with a suitable operating handle 62 for manipulating the same. These bodily movable intermediate feedrolls 57 may be individually adjusted, as for instance, by the means above described, for changing the path of each of the narrow webs to bring all of the webs into proper register at the associating mechanism, irrespective of the width of the narrow webs.

Certain of the bodily movable rolls 57 have a slightly modified device for adjusting them, which device comprises an arm 63 fixed to the rock shaft 59, which arm has a curved slot 64 engaged by the tightening bolt 65, carried by the cross frame.

, The parts are driven from a vertical shaft 66 having a bevel gear 67, which meshes with a bevel gear 68, on a cross-shaft 69. This cross-shaft 69 has a gear 70 which drives the roll 14, through the gears 71, 72,

73. The rolls 9 and 10 are driven from the gear 71, through the gears 74, 7'5, 76, 77. The upper and lower groups of web feed rolls 26 and 39 are driven as follows: The shafts of these rolls 26 and 39 are provided with spiral gears 78, 79, which mesh with spiral gears 80, 81, on the cross shafts 82, 8,3,respectively. These cross shafts 82, 83, are driven from the gear 70 of the cross shaft 69, through the gears 84, 85, 86, 87. The spiral gears 80 and 81 are of suflicient length to permit the adjustment of the rolls 26 and 39 laterally of the machine to the desired amount,'without bringing the spiral gears 78 and 79 out of mesh with their respective spiral gears 80 and 81, thus eliminating the necessity of re-arranging the'driving mechanism for these feed rolls as they are adjusted to suit narrow webs of various widths.

From the above description it will be seen that a web or aplurality of superimposed webs may be fed into the web associating mechanism and the said web or webs divided into narrow webs of different widths according to the widths of the sheets which are to be cut from the said narrow webs. In the drawings the parts are shown adjusted for a series of wider narrow webs, and in Fig. 6 of the drawings in dotted lines the parts are shown in the positions for handling much narrower narrow webs WVhen thewidth of the narrow webs is determined, the slitters are adjusted individually, laterally of the machine, to cut the predetermined width of narrow webs from the wide web or webs. The turners are then adjusted individually laterally of the machine to correspond with the slitters. The upper and lower groups of web feeding rolls are then adjusted individually laterally of the machine to' correspond to the slitters and turners. The intermediate web feeding rolls are then individually laterally adjusted for increasing or decreasing the length of travel of the narrow webs between the web feeding rolls and the web assembling rolls to bring all of the narrow webs into proper register at' the web assembling rolls. 1

Itwill thus be seen that the mechanism includes parts which may be very rapidly and easily adjusted for webs of different widths. It will also be seen that the adjustment of the upper and lower groups of web feeding rolls may be accomplished without disconnecting their gears.

.While I have shown and described a single wide web only as leading into the web associating mechanism, still it is to be understood that two or more superimposed webs may be led into the machine.

It is'evident that various changes may be resorted to in the form, construction and arrangement of the several parts without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the structure herein shown and described, but,

What I claim is:

1. Mechanism including a group of individually laterally adjustable slitters for slit ting a wide web into narrow webs of different widths and a group of individually laterally adjustable turners for simultaneously handling said narrow webs of diflerent widths.
